How may I use those files to do similar within HQ Player? Is it possible? I AssUMe yes.
I wish also to create a 7.2 convolution mapping using Audiolense/RoomEQ/<whatever is documented> and HQ Player. While I understand the learning curves are a bit steep a pointer to documentation for any use cases would be appreciated.
I have a umik-1 and the calibration files so I’m good with giving anything a whirl.
Hi
Until more experienced users are going to respond I’ll post some maybe you’ll play around. I’m kind of a newbie so I’m looking forward to get corrected and learn more
I’m using rew with a mic, I have builded convolution and zip to use in roon but since started using HQP removed them from room. HQP does all the upsampling I think is better to use any correction, headroom there. Only for two channels but there should not be different workflow for loading for 7.2.
On the HQP menu, you have Matrix. There you have 2 options. I have used Convolution with the exported wavs and pipeline with exported text files. First I have used convolution but with pipeline is a bit more flexible as you can save different configurations and switch between then on the fly using desktop control or mobile. Maybe you can do that also with convolution and I do not know. Also with pipeline you can plot the results and that is nice. For the moment I’m correcting only for base, only bringing down the measured peaks. But when I’ll have time I’ll redo the measurements and go further. Sorry as I do not know anything in Audiolense.
I’m trying some screen shots but if you got anything to ask pls ask
Better just get the Elex info from oratory1990’s page, create a .txt file with below format.
In HQP Embedded go to ‘Matrix’ page and upload the .txt file for channels 1 and 2 (left and right).
Save the ‘profile’ with a name that you want. Use the ‘plot’ feature to view the EQ curve before hitting play. Make sure you have enough pre-amp in the text file (or use the gain on matrix page).
Preamp: -9.7 dB
Filter 1: ON PK Fc 22 Hz Gain 9.7 dB Q 0.700
Filter 2: ON PK Fc 250 Hz Gain -1.6 dB Q 1.100
Filter 3: ON PK Fc 980 Hz Gain -2.1 dB Q 2.000
Filter 4: ON PK Fc 2000 Hz Gain 3.3 dB Q 1.700
I really appreciate the pointers.
Is using the txt files preferable to or done in conjunction with the convolution wav files? I see fixed band, graphic , parametric and the wav’s I’m using. Super confusing if I use one, all or some combination. I’ve typed all in manually which I use to learn Roon’s editor has some pain points.
I did this for 4 sets of headphones so I’m looking todo it right™ this time.
In my case I started with convolution because I was following a tutorial with no filters just calculations based on the measurements and exported wav. But switched to txt as is easier to use
logical, but did not figure this with my slow brain. Thanks
The Elex are an odd duck. Drop.com worked with Focal direct to tweak a different headphone. It is a hybrid between an Elear and a Clear. That the first URL had it was shocking honestly.
Caveat: I’m not using HQP myself, but …
… you guys should be aware that PEQ filters are an approximation only, while convolution filters are an exact correction - don’t know if/how HQP is handling filter resampling though, but should be capable to handle that, no?
Yes of course HQP can handle convolution files, like my 65k tap FIR generated by Audiolense XO for speaker correction and XO, and room correction.
Convolution files can also be created from PEQ files, which might be what autoEQ provides? So would the convolution file be better than PEQ in this case? I could be wrong on this assumption/guess
For example REW and Oratory is always PEQ and the convolution filter you get out of it is just conversion of PEQ to convolution filter at given sample rate. So the convolution filter you get from REW is less exact correction than using it’s PEQ settings. In addition, PEQ is always sampling rate agnostic.
Yes, HQPlayer can scale convolution filters to any sampling rate.
But for example for most of these corrections like Oratory and REW are PEQ based. If you then use convolution, you have following path:
PEQ → Convolution filter → HQPlayer convolution filter scale (optional bandwidth expansion) → convolution
Or if you stick with the original PEQ parameters:
PEQ → HQPlayer PEQ
So always consider how your convolution filter started off.
Most optimal correction data is something that it not specific to any sampling rate, but just describes the corrections that should be performed.
- very good performance
